RATCHET DIE-STOCK.

Specification of Letters Patent.

1 Application filed February 10, 1919. Serial No. 275,981.

To all whom it may concern:

Be it known that I, RUE S. HESTAND, a citizen of the United States, residing at Howe, in the county of Grayson and State of Texas, have invented certain new and useful Improvements in Ratchet Die-Stocks, of which the following is a specification.

My invention relates to ratchet die stocks, and more especially to that class de signed for threading pipe in close places, as down in a trench or againstwalls, between rafters, etc., and its novelty, adaptation and many advantages will be fully vunderstood from the following description and claim, taken in conjunction with the annexed drawings wherein like numerals of reference indicate corresponding parts, and in which Figure 1 is a side view of a die stock em-- bodying my invention; Fig. 2 is a plan view thereof, small portions being broken away in both views to show more important features; and Fig. 3 is a detail end view of Fig, l.

eferring to the drawings, 1 represents ordinary threading dies, 2 the die stack, 3 and 4 die adjusting screws, 5 the usual socket or sleeve for bushing 6, and 7 a thumb screw for removably securlng said bushing. All of which are of well known constructlon and require no extended description.

My improvement consists in adding a circu lar enlargement 8 to the outer end of the socket 5, with ratchet teeth 9 formed around its circumference; and also in providing a similar socket 10, with ratchet teeth 11, upon the opposite side of the stock 2. Housings 12 and 13 encircle the enlarged portions, extend rearwardly and converge to connect with a handle 14 which is formed integrally with the housing 12, while 13 is secured to the handle by rivet 15. Double-acting pawls 16 are pivoted upon pins 17 to the extended inner sides of the housings 12 and 13 respectively, and either of their free ends may be brought into engagement with the ratchet teeth 9 and 11 for turning the die stock forwardor back. To actively retain the pawls in either operative position in relation to the ratchet teeth when the handle 1a is oscillated, coiled springs 18, located in sockets 19, carrying pintles 20 that engage notches 21 in the enlarged hub of the pawls are provided. Moving the toes of a pawl from one position to the other, rocks the notch 21, with its pintle, to a position above or below the center of pin 17, when the tension of the expansion springs will respectively, yieldingly retain either toe of the pawl in engagement with the respective ratchet teeth, enabling the turning of the die stock in either direction, right or left as desired.

It will be obvious that changes may be made in the details of the construction and configuration of the invention without departing from the spirit thereof as defined by the appended claim.

Having described my invention and set forth its merits, what I claim as new, and desire to secure by Letters Patent, is

The combination with a socket-extended die stock and a bushing located therein, of a diametrical enlargement of the outward projecting end of the socket, having transversely disposed ratchet teeth surrounding the face thereof, a similar socket extending from the opposite side of the die holding portion of the stock, housings encircling the ratchet portions and connected with a handle, and a double-acting pawl pivotally mounted in each of the extended housing portions for engaging the ratchet teeth.

In testimony whereof I allix my signature.

.RUE S. HESTAND.
